背景 在不同的临床条件下，测量主动脉脉搏波速度 (PWVao)、主动脉增强指数 (Aix) 和中心收缩压 (SBPao) 的重要性已得到证明；然而，有关这些参数的信息很难获得。本研究的目的是评估一种新型、易于应用的示波仪（动脉描记器）的准确性，同时确定这些参数，以防止侵入性测量。方法分别在 16、55 和 22 例患者的心导管插入术期间侵入性测量主动脉 Aix、SBPao 和 PWVao，并与动脉描记器测量的值进行比较。结果我们发现侵入式测量的主动脉 Aix 与示波测量的值之间存在很强的相关性。基于每个患者的逐次搏动或平均值的肱动脉 Aix（r=0.9，P
Background The importance of measuring aortic pulse wave velocity (PWVao), aortic augmentation index (Aix) and central systolic blood pressure (SBPao) has been shown under different clinical conditions; however, information on these parameters is hard to obtain. The aim of this study was to evaluate the accuracy of a new, easily applicable oscillometric device (Arteriograph), determining these parameters simultaneously, against invasive measurements.Methods Aortic Aix, SBPao and PWVao were measured invasively during cardiac catheterization in 16, 55 and 22 cases, respectively, and compared with the values measured by the Arteriograph.Results We found strong correlation between the invasively measured aortic Aix and the oscillometrically measured brachial Aix on either beat-to-beat or mean value per patient basis (r=0.9, P
